ABSTRACT
The present study was conducted at Panna Tiger Reserve of Madhya Pradesh for sero-surveillance for canine parvovirus (CPV), canine distemper virus (CDV) and canine adenovirus (CAV) infections in feral dogs. Biological samples were also collected from the wild carnivore species which were immobilized or died during the study period. Serum samples were subjected for detection of IgG antibodies against CPV, CDV and CAV infections. Additionally biological samples of wild carnivores were subjected to molecular diagnosis of CPV and CDV genes. Seroprevalence for CPV, CDV and CAV infections was observed as 3.5%, 4.4% and 0.89%, respectively, whereas for mixed infections of CPV+CDV, CPV+CAV, CDV+CAV and CPV+CDV+CAV, it was observed as 48.2%, 1.7%, 4.4% and 36.6%, respectively. Sex wise, age wise and distance wise seroprevalence was non-significant in the present study. Seroprevalence for CPV, CDV and CAV infections in cats was observed as 50%, 100 % and 0%, whereas in wild carnivores, it was observed as 100%, 90% and 0% respectively. PCR based diagnosis in the wild carnivore also revealed CDV positive cases. Serological and genomic evidence of pathogens in dogs-cats of buffer villages and wild carnivores of Panna tiger reserve indicated that the viruses may pose a high risk of spillover to wild carnivores. Study also indicated that dog population is immuned to major infectious diseases but can be a threat to the compromised wild carnivore species including tigers
ABSTRACT
The objectives of this study were to investigate growth patterns of Sirohi goat applying the Brody function and estimated the parameters of growth curve including genetic evaluation of growth curve traits. The data used in this study, collected in All India Co-ordinated Research Project (AICRP) on goat improvement, Livestock Research Station, Vallabhnagar, Udaipur, India from year 2009 to 2017 and were included 340 male and 715 female kids body weight measured at birth to 12th month of age in every three months interval. Least-squares means for growth curve parameters of A (Asymptotic weight), B (folding point of growth) and K (maturity rate) were 26.18±3.11 (kg), 0.88±0.00 (kg) and 0.16±0.00 (days), respectively. Fixed effects (cluster, year and season of birth, sex, and type of birth) were significantly influenced the parameters of growth curve. The heritability estimates ranged from 0.02±0.01 (“K”) to 0.40±0.05 (“A”). The genetic correlation between A-K and B-K was negative, which might be due to the compensatory growth effect"
